JOHN H. DUNCAN AND FRANK A. HALE, OF SYRACUSE, NEW YORK..A

CIS'TERN-CLEAN-ER.`

SPECIFICATION forming part of Letters Patent No. 410,159, dated September 3, 1889. Application filed November 26, 1888. ASerial No. 291,902. (No model.)

To @ZZ whom it may concern: y

Be it known that we, JOHN H. DUNCAN and FRANK A. HALE, of Syracuse, in the county of Onondaga, in the State of New York, have invented new and useful Improvements in lowing the air contained in the cleaner to escape upward and causing the pressure of the water to force open a valve in the base of the' cleaner, causing t-he mud and other refuse in the bottom of the cistern to be forced into said opening as the contained air is forced upward out of the cleaner, forming a vacuum; and to this end it consists7 essentially, in a suitable receptacle of desirable size to be easily 1 `raised and lowered and provided near its upper portion with a valve suitably connected to the hand of the operator, whereby the same may be opened when desired, and a valve in the base of the said receptacle, into which the mud is forced when the upper valve is opened.

It furthermore 'consists inthe detail construction and arrangement of the parts, all as hereinafter more fully described, and pointed out in the claims.

In specifying ourinvention referenceis had to the accompanying drawings, forming a part of this specification, in which like letters indicate corresponding parts in all the views.

Figure lis a side elevation of our improved cistern-cleaner, parts thereof being broken away, respectively, at the top and bottom'for the purpose of illustrating the construction and arrangement of the valves. Fig. 2 isla side elevation, partly in section,of a modified form of the upper valve of our improved cistern-cleaner; and Fig. 3 is an elevation of the device for opening and closing the valve illustrated in Fig. 2.

A represents any suitable receptacle of desirable form and construction, preferably adapted to be easily lowered and raised in the operation of cleaning' the cistern, provided at its base A with avalve B and at its top, prefthe receptacle A we provide any suitable handle, (not shown,) secured to a rod or standard D, which is mounted and supported by a collar E, secured to the receptacle Aby suitable braces F, attached thereto in any desir-` able manner.

The standard D is provided with a flange or shoulder D', adapted to abut A against the collar or hub E when the cleaner is being inserted into the cistern and forces the same downward, and the lower extremity D2 of the standard D is provided with an annular shoulder D3, mounted in a suitable en` circling-hub G, secured in any desirable manner uponthe top of the cleaner, preferably in the center thereof, and provided at its top with an annular iiange or ring G, forming a y A stop to the upward movement of the shoulder G3. As the cleaner is being forced into the cistern this shoulder D3 abuts against an aperture a, provided in the top a of the receptacle A, and is securely closed, preventing the escape of the air contained in the recepta-` cle A.

In the base A of the cleaner we provide any suitable valveB, which is openedinwardly, and

when the cleaner hasbeen forced through the water to the bottom of the cisternthe standard D is slightly raised, by means of the handle secured thereto, until the shoulder Ds abuts against the fiange or ring G of the collar G, uncovering t-he aperturea, whereupon the pressure of the water forces the valve B inward and drives out the air through said aperture a into the hub Gin the space G2, interposed between the top d and the shoulder D3 of the standard, whence it is forced outward into the waterthrough apertures b, leading therefrom, and then escapes through the water, producing a vacuum in the cisterncleaner and allowing the mud and other refuse on the bottom of the cistern to ll said cleaner, when the same may be drawn up at will.

For the purpose of readily removing the refuse contained in the cleaner, we preferably hinge or removably secure said bottom A or any other suitable portion of said receptacle, so that the same may be readily opened and the refuse easily discharged from the cleaner.

IOO

In Fig. 2 we have shown a modified form of the upper valve, in which construction the collar D@7 has no vertical movement in its encircling hub and closely fits the space G2, interposed between the flange G and the top a', but is providedrwith an aperture or apertures leading from the bottom g of said collar D3 upward, and adapted to be registeredwith a like opening or openings provided in the collar D3 when the standard D is ltwisted or rotated in said collar, Which is easily allowed, as the collar D is preferably round, and the collar D may be easily turned upon its supporting-hub E.Y

The operation of our improved cleaner will be readily understood from the foregoing, and it will be seenthat without departing from the spirit ofY our invention considerable change may be made in the detail, construetion, and arrangelnent of the paitsmas, foi' instance, the relative arrangement and construction of the top valve maybe varied, providing that the same is normally closed while the cleaner is being forced into the cistern, and may be opened when the same is in the desired position, and any particular form of bottom valve may be used when desired, and

`-the means for discharging the refuse from the cleaner' A may be of any desirable form and construction allowing the refuse to be easily discharged therefrom.

By reference to Figs. l and 2 it will be seen that the construction embodied separately in said figures might be combined in a further modification of our cleaner. In Fig. I the handle has an up-and-down movement, and when in its upward position connects the aperture h in the collar G to the aperture a in the top of the cleaner-receptacle. In Fig. 2 these apertures are connected together by twisting the handle, which in this ligure is shown as having no up-and-down movement; but it will be readily understood that if so desired the aperture b in Fig. l lmight be placed in the collar G su Hiciently high, so that when the handle was in its upward position the said aperture Y1weuld'still be closed until the handle having an opening therein, as shown in Fig. 2,was twisted around, connectin g' the said aperture b and aperture a, as shown in Fig. 2.

It willbe observed that in our construction of the top valve .we rely upon the same being closed by thc buoyancy of Jthe receptacle when the same is being forced into the water, which buoyancy is suiicient to force the J(op of the receptacle 'firmly against the collar D3, securely closing the aperture a provided therein.

This device may also be used to great advantage in cleaning wells or other receptacles or tanks upon the bottom of which sediment or refuse matter collects which it is desirable .per valve when the handle is turned, substantially as and for the purpose set forth.

2. In a cistern-cleaner, the combination of the receptacle having a valve in its'base, with an aperture or valve in the upper part ot" the receptacle, a flange-collar above said aperture, and a handle movably mounted in the collar adjacent to said valve and actuated to operate the same, substantially as described.

3. In a cistern-cleaner, the combination of the receptacle A, having a valve in its base, with an aperture or opening a in the upper part ot the receptacle, a collar above said aperture and provided with openings l), andthe handle movably mounted in the collar adjacent to said aperture and actuated to connect a passage from the opening a inY the upper part of the receptacle and the opening b in the collar, substantially as and for the purpose set forth.

4. In a cistern-cleaner, the combination of the receptacle A, having a valve in its base and an aperture or opening a in the upper part of the receptacle, a collar G, mounted above said aperture and provided with openings b, and a ange G, provided on the collar G, With the handle D, movably mounted in `the collar G, the annular shoulder D3, interposed between the iange G and the cleaner-receptacle for closing and opening the apert-ure a, substantially as and for the purpose setfort-h.

5. In a cistern-cleaner, the combination of a receptacle having a valve in its base, and an aperture or valve in its upper. part, with the collar G, mounted above said aperture, a handle D, movably mounted in the collar G, adjacent to said aperture, for opening and closing the same, and a collar E, above the cleaner-receptacle and braced thereto vfor supporting the movable handle D, substantially as and for the purpose specified. A

In testimony whereof we have hereunto signed our names, in the presence of two atF testing witnesses, at Syracuse, in the county of Onondaga, in the State of New York, this 24th day of November, 1888.
